Photonic-based A/D conversion has received and continues to receive considerable attention as an alternative approach to providing enhanced resolution and speed in high-performance applications. Some of the potential advantages of using photonic technologies are high-speed clocking, broadband sampling, reduced mutual interference of signals, and compatibility with existing photonic-based systems. This book provides a comprehensive look at the application of photonic approaches to the problem of analog-to-digital conversion. It shows progress made, discusses present research, and gives a glimpse of potential future technologies.

Single up-to-date monograph in this fast progressing area available Focusses on photonic A/D conversion and describes also future development End-of-chapter summaries Highly illustrated with many examples Includes supplementary material: sn.pub/extras
